Objective To investigate the effect of CaMK Ⅱ expression on apoptosis of rat hepatocytes BRL-3A.Methods Rat BRL-3A cells were stable passage were cultured.The CaMK Ⅱ γ protein (LV-CaMK Ⅱ γ group) and CaMK Ⅱ γshRNA (shRNA group) lentiviral expression systems were constructed.The corresponding blank vectors (LV-NC group and shRNA-NC group) and normal saline (CON group) were perfused into the control groups.The expression levels of CaMK Ⅱ,Cyt C and MF proteins were detected by Western blotting,and the apoptosis rate of BRL-3A cells was measured by Tunel method.Results The protein expression of CaMK Ⅱ,Cyt C and AIF in LV-CaMK Ⅱ γ group was significantly higher than that in CON group (P＜0.05).The protein expression of CaMK Ⅱ,Cyt C and AIF in shRNA group was significantly lower than that in CON group (P＜ 0.05).There was no significant difference among CON group,LV-NC group and shRNA-NC group (P＞0.05).At the same time point,the apoptosis rate of hepatocytes in LV-CaMK Ⅱ γ group was significantly higher than that in CON group (P＜0.05).At the same time point,the apoptosis rate of hepatocytes in shRNA group was significantly higher than in CON group (P＜0.05).There was no significant difference in the apoptosis of hepatocytes among CON group,LV-NC group and shRNA-NC group (P＞0.05).Conclusion The specific CaMK Ⅱ signaling pathway can inhibit the apoptosis of BRL-3A cells,while the enhanced CaMK Ⅱ signaling pathway promotes the apoptosis of BRL-3A cells.

Objective To probe the effect of applying montelukast combined with pidotimod in asthma of aged patient.Methods 120 cases of asthma in non-acute episode phase were randomly divided into three groups.Group 1 was treated with montelukast combined with pidotimod,group 2 was treated with montelukast,and the control,namely group 3 was ketotifen.All cases were treated by means of intensification therapy including glucocorticoids,?_2 agonists and some necessary anti-infection during acute episode.Results After 10 weeks treatment,both group 1 and 2 made notable improvement with respect to many asthma control parameters(P
